What It Does

Generates cryptographic hashes (MD5, SHA-1, SHA-256, SHA-512) for one or more files, creating an evidence-style manifest for file verification and documentation.

How It Works

Uses the Web Crypto API (SubtleCrypto.digest) for SHA hashes and a pure JavaScript MD5 implementation. Processes files sequentially with a progress indicator.

Use Cases

Evidence documentation for digital investigations
File integrity verification after transfers
Chain-of-custody style inventory
Proving files have not been altered

Privacy
